JJ,
All that it will take for the shares to be reinstated in the shareholder's account is an order from Judge Silverstein upon a motion from an interested party. Contrary to some speculation here, delisted shares cannot be "lost". They must be kept as digital records by the DTC until such time a bankruptcy court declares them void and null or reinstated. In addition, the Canadian government put an anti-money laundering regulation in place that requires company share records to be kept by the issuer and made available by request to the Canadian Revenue Service, the Royal Mounted Policy, and a court with jurisdiction, which in this case are the CCAA and the Chapter 15 Courts.
On the time needed to end this saga, there is an interesting dynamic at play here: KRY and Tenor will want to end it "yesterday" for reasons I cannot discuss here, while the shareholders will be much better off not accepting a compromise until it complies with what is required by law and equity. And a solution at law and in equity tilts distinctly to the shareholder’s side.
